Think Amazon.com's Kindle is devoid of advertising? Think again. Showtime was debuting a new series, Nurse Jackie, one week before HBO's season premiere of True Blood. Showtime advertised its premium cable series via Kindle by offering the pilot script of Nurse Jackie as a free download. The script included show scheduling, and users could watch the pilot episode on Amazon.con or Sho.com once the script was read. Two days after the launch, the Nurse Jackie script made its way into the top 20 Kindle downloads, and ratings for Nurse Jackie gave Showtime its highest ratings for an original series.
